Which Behr is best?

Before stopping by Ikea today, we also went to pick up color samples at Home Depot. Of course we can't see the samples in the house yet, but we want to try and get a couple rooms painted in the weekend before we move our stuff in. I've decided to paint pretty much the whole house white and then use accent walls with solid colors, wallpaper, or murals here & there. We looked at a lot of whites, pulled our favorites, and then also compared them to the counter we chose. We decided to go with Behr's Frost. It's a nice bright white- but not too harsh.

I also went ahead and pulled some accent color swatches. I know I want a yellow wall somewhere... somehow. I know the TV nook and possibly part of a bedroom or bath with be black. Some of the other accents will be based on different posters or things I already have. None of those choices will be made for sure until after everything else is settled in, but I figured I'd pick up some swatches anyway.

I did a little mockup of what I'm thinking for the kitchen facelift. Of course the darkwoods and maple cabinets stay, and the counters will be grey/white with a graphic pattern. The walls will be a bright "Frost" white. I'm thinking an ice blue would be a nice accent for the kitchen/dining, but I'm not sure yet. I've also been thinking of painting an acid green backsplash & then covering it with plexi so that I can easily change it out (the green would match my Orla Keily pear accessories). My other kitchen & dining accessories are all red, brown, cream, and stainless. The only thing I've settled on is Frost for everything...

The digital versions of Frost and Grape Green aren't nearly as bright and crisp as their physical counterparts...
